The Toyota Prius plug-in has a 540-mile range while the Chevrolet Volt has a 380-mile range

After receivng an EPA rating of 100 miles-per-gallon equivalent (MPGe) city/highway combined, Ford's C-MAX Energi has now been named the king of range with 620 miles per tank/charge.

According to Ford, the C-MAX Energi crushes the competition with an EPA rated 108 MPGe city and an EPA rated 620-mile overall driving range. The Energi is also capable of traveling 21 miles in all-electric mode and has 195 horsepower with a fully charged battery.

The Toyota Prius plug-in, on the other hand, has a 540-mile range while the Chevrolet Volt has a 380-mile range.

Not only will the C-MAX Energi be America's most fuel efficient vehicle with the longest range, but it will also be the most affordable. It has a starting price of $29,995, but is eligible for the federal tax credit. The EPA label also noted that customers could save almost $7,000 in gas over the course of five years with the C-MAX Energi.

“C-MAX Energi is America’s most efficient utility vehicle, a great symbol of how Ford gives customers the power to choose leading fuel-efficiency across our lineup with gas prices spiraling upwards of $5 a gallon in some parts of the country,” said John Davis, C-MAX chief engineer. “The C-MAX Energi’s leading range also means customers can spend more time on the road and more money on their priorities instead of at the gas pump.”

Ford also mentioned that the C-MAX Energi's range was designed to address congestion problems. A longer electric range means no wasted fuel while sitting in traffic.

The C-MAX Energi, due out this Fall, will also offer many of Ford's features like SYNC with MyFord Touch, MyFord Mobile, ECO Cruise and SmartGauge with EcoGuide.
